  11
  12         * aclocal.m4 Include ../../gettext.m4.

  22         optimization produces a warning, which interferes with compilation
  23         with -Werror.)

  35         the variable is referenced in the submake, not when the submake's
  36         arguments are expanded.
  37         (cgen.sh): Be prepared for the 'cgen' argument to contain spaces.
  38         (arch, cpu, decode, cpu-decode, defs, desc): Place the name of the
  39         application Scheme script directly after ${cgen}; don't precede it

5068
5069         * aclocal.m4:  Remove Make-common.in from dependencies.
5070         * (distclean):  Remove targ-vals.def.
5071
5072         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
5073         into here.  Makes insertion into makefiles easier.  Also, change
5074         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5075         targ-map.o, and run are built.  They are now built in the
5076         individual simulator directories, taking sources from ../common as
5077         necessary.  This replaces the merging of libcommon.a into
5078         linsim.a, which was problematic for the WinGDB build process.
5079         * run.c:  Include config.h from . instead of ../common.
5080         * Make-common.in:  Remove.  It's no longer necessary.

5100         * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
5101         specific.

5110         Only process -p/-s ifdef SIM_HAVE_PROFILE.
5111         Parse program name from argv[0] and use in error messages.
5112         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
5113         Add support for incomplete h8/300 termination indicators.
5114         (usage): Make more verbose.
5115         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

5152
5153         * run.c (main): Removed SH specific comments, so source is
5154         generic. Also updated to only load relevant sections. Moved
5155         sim_open() to after callback attach (to match GDB).
